Over a period of many years, I will make strides in improving myself physically, only to be set back significantly. I am wondering if anyone has any guidelines regarding exercise. I seem to suffer two types of problems. One is pain that comes on gradually through the course of exercise, or the next day, and the other (far less frequent) is pain that comes one sharply during exercise. In the case of the former, if I were to pick up a weight far heavier than I'm use to lifting, eventually I would feel muscle pain from doing reps. If I didn't feel it at the time, I'd feel it the next day. I'm familiar with the harmless "DOMS" pain. I'd experience pain over the course of a month, though. How would I tell strain from TMS? As for the sudden, sharp pains, I think that they are often real injuries. I can feel a "pulling" sensation within muscle when this happens. The last time this happened was when I'd walked about 1/4-1/2 mile total through the course of a day. This was all I had the strength in my legs to do. Just as I was getting ready to go to bed, I stood up from a seated position rather quickly. I then felt this "pulling" sensation in my calf. Would exercising your body to the point where it can't take much more set you up for a muscle strain? I went to a TMS Dr. at great expense and hassle, and the visit was useless. He said that he refused to speculate as to what might be a real injury, and what might be TMS. The whole point of the visit was to get some sort of guidelines for exercise. He said that I should push through pain, but not too much. I know my issues are mainly neurological, since I have the tender points. I don't know if this is the result of brain damage or simple TMS. During the most stressful period of my life theretofore, I was in a crash in which I hit my head. I didn't lose consciousness, but sustained a concussion. Any ideas? Thanks.
